I purchased a freeze plug heater to help keep the engine warm as the temps where I live have been dipping below -30 but I haven't been able to locate where exactly I am supposed to plug it into. I haven't been able to find any pictures or videos on where the correct location is. I have a 2013 Outlander with 4x4. A 2.4L V4 engine. Any help would be greatly appreciated! I currently have a battery blanket on the battery to help start the engine.
